UK IVF Birth Rates Fall With Age Using a Patient's Own Eggs
This 2017 UK report tracked 54,760 patients across 75,425 fertility treatment cycles at every licensed clinic. Birth rates fell with age for patients using their own eggs. Frozen embryo transfers outperformed fresh ones for the third year running: 23% versus 21% per embryo transferred.
Key Findings
- Cycle counts climbed in 2017: 69,822 for IVF, up 2.5%, and 5,603 for donor insemination, up 3%, compared with the prior year.
- Donor insemination births reached 14% per treatment cycle in 2017, similar to 2016.
- For the third straight year, frozen transfers outperformed fresh ones: 23% born per embryo transferred against 21% for fresh.
- Among patients under 35 using their own eggs, 30% of fresh cycles and 27% of frozen cycles ended in a birth, per embryo transferred.
- Multiples made up around 24% of IVF births in 2008 and 10% in 2017, the first year the regulator's 10% target was met.
Interpretation
This is a registry report. Every licensed UK clinic must send its yearly data to the HFEA, the UK's fertility regulator. The 2017 numbers come from over 75,000 cycles across every licensed clinic. But the report does not follow one patient's full story. The data do not say why one cycle worked and another did not. The report also does not compare treatment with no treatment at all. The IVF birth rates only cover cycles that reached embryo transfer. Everyone whose IVF cycle stopped earlier is left out.
RRM Context
A registry like this counts outcomes. It does not look at what caused each patient's infertility. IVF proceeds without establishing that cause. Restorative reproductive medicine aims to find and treat the cause. One number here shows why that gap matters: birth rates using a patient's own eggs decrease as age rises. By contrast, this report's donor insemination rate, 14% per cycle, sits close to the report's cited rate for fertile couples conceiving "naturally," 11.6%.
